CONNECTOR HUB APPARATUS FOR CATHETER AND METHODS OF USE

摘要

A hub assembly is provided for accommodating a medical professional to grip and manipulate two components of a catheter hub and move one component longitudinally relative to the other, then removably engaging the two components of the catheter hub to restrict movement there between. The two catheter hub components include a proximal hub and a distal hub. The proximal hub and the distal hub are configured to removably engage with one another. The proximal hub is affixed to a first catheter member, such as a multi-lumen catheter, while the distal hub is affixed to a second catheter member, such as a sheath. The first catheter member and the second catheter member are cooperatively engaged and concentric with one another. Relative movement of the proximal and distal hubs translates into relative movement of the first and second catheter members.

主权项

1. A method of removably coupling a catheter hub, comprising the steps of:
a. providing a catheter hub comprising b. disposing a multi-lumen catheter through the core member; c. disposing the core member through central mounting section of the proximal hub member such that the annular detent of the core member is distal the distal end of the central mounting section and the o-ring interfaces with the longitudinal lumen of the sealing member; d. sliding the distal end of the multi-lumen catheter through the internal lumens of the sealing member and the distal hub member such that the hemostatic valve creates a fluid barrier around the outside of the multi-lumen catheter; and e. translating the proximal hub member and the distal hub member towards each other such that the resilient projection enters the open distal end of the proximal hub member, deflects radially inwards, and returning to its original non-deflected state, thereby engaging with the distal interfacing surface of the catch and coupling removably the distal hub member and the proximal hub member.
